The Criminalisation of Migration in Europe: A State-of-the-Art of the Academic Literature and Research. CEPS Liberty and Security in Europe No. 61, October 2013

In the last 30 years, a clear trend has come to define modern immigration law and policy. A set of seemingly disparate developments concerning the constant reinforcement of border controls, tightening of conditions of entry, expanding capacities for detention and deportation and the proliferation of criminal sanctions for migration offences, accompanied by an anxiety on the part of the press, public and political establishment regarding migrant criminality can now be seen to form a definitive shift in the European Union towards the so-called ‘criminalisation of migration’. This paper aims to provide an overview of the ‘state-of-the-art’ in the academic literature and EU research on criminalisation of migration in Europe. It analyses three key manifestations of the so-called ‘crimmigration’ trend: discursive criminalisation; the use of criminal law for migration management; and immigrant detention, focusing both on developments in domestic legislation of EU member states but also the increasing conflation of mobility, crime and security which has accompanied EU integration. By identifying the trends, synergies and gaps in the scholarly approaches dealing with the criminalisation of migration, the paper seeks to provide a framework for on-going research under Work Package 8 of the FIDUCIA project.

The Legal Construction of Membership: Nationality Law in Germany and the United States. CES Germany & Europe Working Papers No. 00.5, 2000

The argument of this paper is that several empirical puzzles in the citizenship literature are rooted in the failure to distinguish between the mainly legal concept of nationality and the broader, political concept of citizenship. Using this distinction, the paper analysis the evolution of German and American nationality laws over the last 200 years. The historical development of both legal structures shows strong communalities. With the emergence of the modern system of nation states, the attribution of nationality to newborn children is ascribed either via the principle of descent or place of birth. With regard to the naturalization of adults, there is an increasing ethnization of law, which means that the increasing complexities of naturalization criteria are more and more structured along ethnic ideas. Although every nation building process shows some elements of ethnic self-description, it is difficult to use the legal principles of ius sanguinis and ius soli as indicators of ethnic or non-ethnic modes of community building.
